Description

[Detailed description of the invention] "Industrial application field" This invention relates to a unit type curtain wall that is attached to the wall of a building.

``Prior Art'' A unit type curtain wall is a curtain wall with a structure in which a unit frame made in the shape of a frame in advance is attached in a mullion, and the wall of the building is covered with the unit frame.

Figure 4 shows the mounting structure of a conventional unit type curtain wall. In the figure, 1 is a mullion, and 2A and 2B are unit frames supported by this mullion 1.
The mullion 1 is attached vertically to a portion of the building that will become the outer wall of the building. The mullion 1 requires considerable strength. For this reason, conventionally steel materials are used.
This example shows the case where H-beam steel is used.

The unit frames 2A, 2B are assembled in advance into a frame shape, and brackets 3 are provided on the indoor side surfaces of the unit frames 2A, 2B, and the unit frames 2A, 2B are attached to the mullion 1 via the brackets 3. The unit frames 2A and 2B are equipped with airtight packing 4 on their outer peripheries, and the airtight packings 4 are joined to the airtight packings 4 of adjacent unit frames, thereby maintaining airtightness and waterproofing between the unit frames 2A and 2B. It is said that In addition, a wet sealing material 5 is filled on the outdoor side of the airtight packing 4, and the sealing material 5 and the airtight packing 4 form a double waterproof structure.

There are various types of unit frames. In the illustrated example, the fixed unit frame 2 is fitted with the glass 6.
A and a movable unit frame 2B used as an opening/closing window are shown.

``Problem that the invention aims to solve'' In the conventional unit type curtain wall, brackets 3 are attached to the unit frames 2A and 2B, and the brackets 3 are attached to the bolts 8 and nuts to the clasps 7 provided in the mullions 1. It is installed in 9.

Therefore, when installing the unit frames 2A, 2B in a mullion, it is necessary to insert the bolt 8 into the hole formed in the bracket 3 and the clasp 7, and to screw the nut 9 into the bolt 8. Therefore, until the bolt 8 is inserted into the bracket 3 and the clasp 7 and the nut 9 is attached to the bolt 8, the unit frames 2A and 2B must be suspended, so the lifting device such as a crane or winch is restrained. This has the disadvantage that the installation time for the unit frames 2A, 2B becomes long.

Further, the mullion 1 is exposed on the indoor side, but since it is made of steel, it looks unsightly, so it is necessary to cover it with a cover 11 made of an aluminum plate or the like. There is also a drawback that the cost is increased due to the manufacturing cost of the cover 11, the labor required for attachment, etc.

The purpose of this invention is to provide a unit type curtain wall that can shorten the construction period required for assembling the unit frame.

``Means for solving the problem'' In this invention, A. A mullion made of a hollow aluminum member, B. A wave protruding from this mullion toward the outside of the room, and C. A wave formed from the tip of the wave protruding in both orthogonal directions. a flange; D a slit formed in this flange; and E a bracket that projects from the indoor side surface of the unit frame, contacts the wave through the slit and engages with the end of the slit, and temporarily fastens the unit frame. , F A unit type curtain wall is constructed by the bolts and nuts that fasten this bracket to the wave.

``Function'' According to the unit type curtain wall of this invention, the unit frame can be temporarily fixed by providing a notch in the bracket and engaging the notch with the end of the slit formed in the mullioned flange.

In this temporarily fastened state, a bolt is inserted into the hole formed in the bracket and the wave, and the installation is completed by tightening with a nut.

Therefore, once the unit frame is temporarily fastened, there is no need to hang the unit frame, and a lifting device such as a crane or winch can begin the work of transporting the next unit frame. As a result, the assembly speed of the unit frame is improved, and the construction period can be shortened.

Furthermore, since the bolts are inserted while the unit is temporarily fastened, the unit frame is supported more stably than when it is suspended by wires. This also has the advantage of making it easier to insert the bolts.

In addition, since the mullion in this invention is constructed from a hollow aluminum member, it is possible to expose the mullion as it is indoors by applying a treatment such as painting on its surface in advance, and it is possible to use a cover that closes a small gap. The cost required for the cover can be reduced by simply preparing one.

``Example'' Figure 1 shows an example of a unit type curtain wall according to this invention.

1 in the figure indicates a mullion. In this invention, the mullion 1 is a hollow member formed from an aluminum profile. A wave 1A is provided protruding from one surface of the hollow member, that is, the surface facing the outdoor direction. wave 1
At the tip of A, a flange 1B is formed to protrude in both directions orthogonal to the protruding direction of the wave. These waves 1A and flange 1B are formed integrally with the mullion 1 from an extruded aluminum material.

2A and 2B indicate unit frames. 2A is a fixed frame into which the glass 6 is fitted, and 2B is a movable unit frame that becomes an opening/closing window. 12 is the movable unit frame 2B
This figure shows the hinge that supports the opening and closing of the movable shoji installed on the screen.
In this example, the hinge 12 is mounted in a recess provided on the outer periphery of the unit frame, so that the hinge 12 is not visible from the outside. An airtight packing 4 is attached to the outer periphery of each unit frame 2A, 2B, and the airtight packing 4 is pressed against each other to maintain airtightness and waterproof structure. Further, the outside of the airtight packing 4 is also filled with a wet sealing material 5, and the sealing material 5 and the airtight packing 4 provide a double waterproofing structure between the unit frames 2A and 2B. The structure of this part is the same as the conventional one.

This invention is characterized by a structure in which a notch 3A is provided in the bracket 3 provided on the indoor side surface of each unit frame 2A, 2B, as shown in FIG.

In other words, the bracket 3 is for each unit frame 2A, 2B.
For example, four brackets are provided on the indoor side surface of the brackets 3 as shown in FIG. The bolt holes formed in the bracket 3 and the bolt holes formed in the bracket 3 are aligned. A notch 3A is formed on the lower side of the bracket 3, and this notch 3A is connected to the slit 1.
Engage with the lower end of C.

A U-shaped member 3C is integrally provided on the rear end side of the bracket 3, and this U-shaped member 3C is inserted into the bag-shaped groove 13 provided in the unit frames 2A and 2B.
It is fixed in that position with screws 14.

When the notch 3A of the bracket 3 is engaged with the lower end of the slit 1C and the unit frames 2A and 2B are temporarily fixed to the mullion 1, the bolt insertion hole of the bracket 3 and the bolt insertion hole formed in the wave 1A are aligned. ing. In this state, the unit frames 2A, 2B are attached to the mullion 1 by inserting the bolts 8 and tightening the nuts 9.

After tightening the bracket 3 to the wave 1A with the bolt 8 and nut 9, the mullion 1 and flange 1B are
The cover 15 is fitted into the gap between the unit frames 2A and 2B, and the installation of the unit frames 2A and 2B is completed.

``Effect of the invention'' As explained above, according to this invention, the bracket 3 is provided with a notch 3A, and the bracket 3 is inserted into the slit 1C, and the notch 3A of the bracket 3 is engaged with the lower end of the slit 1C. Because of this, the unit frames 2A and 2B can be temporarily fastened. In this temporarily tightened state, attach bolt 8 to bracket 3.
Just insert it into the bolt hole formed in wave 1A and tighten it with nut 9, so unit frame 2A, 2
There is no need to suspend B by the lifting device forever. Therefore, once the elevating device has carried the unit frame to a state where it is temporarily fixed, it can go to pick up the next unit frame, and the assembly speed of the unit frame can be improved. As a result, the advantage of shortening the construction period is obtained.

Furthermore, since this invention has a structure in which the cover 15 can be fitted with one touch, the work of attaching the cover 15 is easy. In addition, since the cover 15 only needs to close a small gap, the manufacturing cost of the cover is low, and together with the shortening of the construction period, a reduction in the overall cost can be expected.
